Gary Lauder is the co-creator of the Socrates Society at the Aspen Institute along with his wife, and I am happy to say that I've been a part of and enjoy their events.
Gary spoke at this year's TED about changing from stop signs to roundabouts like they have in Europe. Great presentation and great idea! Summary from TED:
Fifty percent of traffic accidents happen at intersections. Gary Lauder shares a brilliant and cheap idea for helping drivers move along smoothly: a new traffic sign that combines the properties of "Stop" and "Yield" -- and asks drivers to be polite.
